MACHINE FOR COVERING WEBBING FOR BOOT-STRAPS.

SPECIFICATION forming part of Letters Patent No. 453,976, dated June 9, 1891. Application filed January 10, 1891. Serial No. 377,372. (No model.)

T0 [0% whom it may concern:

Be it known that 1, WILLIAM C. RAND, a citizen of the United States, and a resident of Lewiston, in the county of Androscoggin and State of Maine, have invented a new and useful Improvement in Machines for Covering W'Vebbing for Boot-Straps, of which the following is aspecification, reference being had to the accompanying drawings.

My invention relates to machines for covering webbing, designed especially for bootstraps with paper or the like to protect the webbing from being soiled during the manufacture of the boots and while otherwise exposed.

The object of the invention is a machine which will automatically wind the paper transversely around the strip of webbing as many times as desired,preferably two for each strap, paste the paper so wound, cut the paper thus wound from the continuous strip of paper, and put around the continuous strip of webbing such coverings at the intervals required so that each strap will have the parts thereof exposed and covered as desired.

My invention consists in the devices and combination of devices hereinafter described, and specifically pointed out in the claims.

In the drawings, (four sheet-s,) Figure 1 is a side elevation, Fig. 2 a front elevation, and Fig. 3 a plan view, of so much of a machine embodying my invention as is sufficient for an illustration of the same. Fig. 4 is a vertical section of certain parts, taken in the direction of lines 1 1 in Fig. 3.

The machine shown is designed to wrap paper A twice around the webbing B for each strap, and to have the carrier C, which consists of two plates or wheels at and I) joined firmly together, as by means of braces 0, make three revolutions in the direction of the arrow, while the necessary operations are performed on the portion of webbing required for one strap. Power may be applied by means of a pulley D on a shaft d, on which is a pinion e, which engages with a gear E 011 a shaft f. The shafts cl and f have bearings on the frame of the machine, as shown. While the carrier C makes three revolutions, as above specified, the shaft f and gear E make one, motion being conveyed to a pinion g, fixed to the carrier to revolve about the same center, and in engagement with the gear E. The carrier has a hollow shaft or hubs h,

which revolve in bearin gs i, fixed to the frame,

and which have openings concentric with the hollow hubs, as shown. A roll of the webbing is placed on a stud j to revolve freely thereon, this stud being fixed to the stationary frame by means of a stand 70. A roll of paper A is placed on a rod or stud Z to revolve freely thereon, this rod or stud being supported by the revolving carrier. The webbing is fed along, as required, by being drawn nearly or quite centrally through the opening in the hubs by means of two feed-rollers m and n, the webbing being directed to the center of said hubs by means of a guide 0, and passing between two clips 19 and q, extending longitudinally with them. The lower q of these clips remains stationary, being fixed at one end to a stand 0". The upper 13 of these clips is pivoted at one end to the stand 0', to swing slightly upward while continuing longitudinal with the other clip. This clip is swung by means of a lever 3, rod 25, lever a, pivoted at o, and a stud 20, hearing on a cam F on the shaft f. After the webbing has been drawn along by the rollers m and n a sufficient distance the clip 1) is swung to press down on the webbing, and after the paper has been wound the required number of times around the clips and webbing between them, pasted, and the tube of paper thus formed has been slid along from off the clips the clip 13 is swung up. The strip of paper extends from the roll thereof to and between two flexible plates 0: and g, each fastened at its outer end to a rod or stud .2, fixed to the carrier C,

the outer ends being at a distance apart, and the inner ends adjusted so as to spring one to the other. The one a: of these plates is of such length that the inner end will drag on the upper clip 13 when the latter is swung up and the carrier is in motion, but will spring down so near the lower clip g as to cause the end of the paper thereat to fallon the clip q or Webbing, and hence be pinched between these clips when the clip 19 is swung onto the clip q. On the continued revolution of the carrier the paper will be wound around the clips j) and q and the webbing between them.

On the shaft f is another cam G, being a groove in a disk, as shown, in which moves a stud a on alever ll, pivoted at-b and having pivoted thereto a rod 1. The other end of this rod is pivoted to a lever J, which is pivoted to a fixed stand at c, and has fixed thereto at the other end of the pivot at c an arm K. To this arm K is pivoted another lever L at (1', there being a slot in the lever L for the movement of the pivot d. The lower end of the lever L is also pivoted to the fixed stand. To the outer ends of the arm K and lever L is pivoted a short lever M, as shown, the outer end of which carries a dauber. To the lever J is also pivoted a rod N at f. The other end of the rod N is pivoted to a short lever O, which is pivoted to a fixed stand at g. The lever O carries a pad h, which is located at a suitable position above the fixed box P for the paste.

The operation of the cam G, levers, and rods just described is such that after the paper has been wound about the clips 1) and q and the Webbing the dauber will be carried down onto the paper lying on the upper clip 19 to leave paste thereon, and Will then be carried back and swung over to meet the pad 7i, this pad having in the meantime been swung down so as to dip into the paste-box P.

Dotted lines at 2 in Fig. 1 indicate a position of dauber and levers connected thereon while moving toward the clips, and dotted lines at 3 in the same figure indicate the pad while in the paste-box.

To the carrier 0 is pivoted at t" a lever Q, to the inner short arm of which is pivoted at j a bar R, which slides in guides, as at fixed to the lever S. The lever S is pivoted to the carrier 0 at m. To the lever S is fixed a blade T and to the bar R- a bladeU. These blades are set with reference to each other to the clips 13 and q and to the plates at and y, as shown, and so as to cut, when brought together as a pair of shears, the paper between them.

To the lever S is pivoted, at a, a presserV, which has a slot, and is pivoted at o to the bar R.

The lever Q is operated by means of a pin 19 thereon, which moves in the cam or slot \V. This cam is only in position to receive the pin 17* during a certain part of the time, the arm or lever bearing the same being pivoted to the frame at q to swing as required. This arm or lever is swung by means of a cam X on the shaft f and lever 'Y, pivoted at 1", one end of this lever bearing a studs, which moves inthe slot of the cam X, and the other end of the lever working against a pin t on the arm oi lever of the cam W.

The operation of the cams X and \V, levers, rods, blades, and presser just described is such that after the paper has been wound around the clips and webbing therebetween a suflicient number of times-two in this case-the prcsscr V comes down onto the paper, pressing the latter onto itself and the upper clip 11, so as to cause the paper to adhere, as required, by means of the paste previously put thereon. Thereafter the blades come together, cutting the paper strip, leaving the tube of paper formed by the several windings and by the pasting on the clips and the webbing.

By means of miter-gears a and v a shaft 00 is driven at the same speed with the shaft f. On the shaft w is a wheel having a camgroove Z, in which moves a pin g on a lever A, pivoted at .2. To the other end of this lever is pivoted a slide bearing a rack 13, which engages with apinion C. This pinion is located concentric with the shaft of the feed-roller a. The connection of this pinion and the feed-roller or shaft thereof, details of which being inclosed in the casing D, are not shown in the drawings, is such as is well known for the purpose of getting an intermittent revolution of a wheel or shaft in one direction through means of another wheel or shaft moving alternately in reverse direct-ions.

The feed-roller m is caused to revolve with the roller a by means of the gears on their several shafts, as shown. Thus by means of the cam Z the rack B, and gears the feedrollcrs m and n are caused to revolve in the direction of the arrows when required-name- 1y, to draw along a suliicient length of webbing for one strap having wound thereon paper for the required part thereof, and therefore to draw into position another length of webbing for another strap to receive the paper as before, and so on.

Adjustment of the several parts of the mechanism may be such as is shown and required and as will be apparent to a skilled mechanic. So, also, there may be modification of the mechanism without departingfrom the invention, the several operations of which may be summed up as follows: The webbing is drawn from a roll on a stationary support. The paper is drawn from a roll which is supported by a carrier. This carrier revolves about a central line at which is that part of the webbing operated. upon. The webbing passes between clips longitudinal therewith and closed onto the same, so that the papcris wound around both the clamp formed by the clips and the webbing. The clips also hold the free end of the paper, which is forced t-herebetween. The paper is wound once around, pasted, wound again around, and then pressed and the strip cut so as to form a tube. The webbing is drawn along intermittently to remove, as required, the part having the desired covering of paper thereon, and to put into position. the part to be operated on.

I claim as my invention 1. In a machine for covering webbing with paper, the combination of clips pivoted with reference to each other and on a stationary support for holding the webbing, and a car- ICC rier supporting the paper, revoluble about a central line at which is that part of the webbing which is held by said clips, substantially as set forth.
